CALECHE develops a decision support system (DSS) for renovating historic buildings, emphasizing a people-centered, holistic, and digitalized approach. The DSS integrates specific protocols for initial evaluations, heritage, energy, structure, engagement, and monitoring, ensuring compliance with cultural value protection regulations. CALECHE focuses on improving key technologies like interior bio-insulation, window conservation, and BIPV, demonstrating the link between innovation and heritage renovation. The work is showcased across four examples and accessible on the Historic Renovation HUB website.

STBA’s role is to lead the coordination on:

• A literature review placing the approach in a theoretical context
• A review of existing tools and methodologies placing the approach in a practical context
• Stakeholder engagement capturing feedback on the identification and weighting of values and benefits as well as analysing trade-offs between various benefits and impacts
• Bringing those threads together to define the key features and write the specification to this multi-criteria decision support system tool to be hosted on a Historic Renovation Hub

Other partners will be working on integrating BIM, AI, a repository of retrofit solutions, wider stakeholder engagement, and dissemination and communication, as well as four casestudies for pilot study – including individual buildings as well as areas, where outputs will be analysed over a range of factors, heritage and technical.
